ON4UN’s book is far more instructive generically about a T vs an inverted L under efficient ground systems.

This issue has little to do with the type of counterpoise/radial system, 
except to the extent that the counterpoise/radial system affects ground 
losses. Also, your understanding of how ground affects verticals is 
flawed, as indicated by your earlier posts in this thread. That said, a 
technical disagreement is hardly a personal attack.

BTW -- the ON4UN book, which I've read and learned from, has the same 
shortcoming as other ARRL publications in displaying and interpreting 
the results of modeling noted in my previous post, changing the subject 
line.
